WATER-CLOSET TANK.

'o cf/ZZ w 750m t may concern Be it known that I, MICHAEL MAUER, a citizen of the United States, residing at Detroit, county of lVayne, State of Michigan, have invented a certain new and useful Tmprovement in l/VatenCloset Tanks, and de? clare the oliowing to be a full, clear, and exact description of the same, such as will enableothcrs skilled in the art to whichV it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to water closettanks and especially to water-closet tanks of that variety which is operated by an air valve, the tank being an air-tight inclosure so that opening of' the air Valve releases the air pressure in the tank and allows the inflow of water.

The invention consists in the. arrangement of elements and the mechanism hereinafter to be described. i

In the drawing, the view is a vertical cross section of a water-closet tank showing the apparatus in elevation.

a designates a tank which is an air-tight inclosure; Z) a tubular housing extending from the outside of the tank. In the threaded opening in the end of this tank is screwed the plug c having a passage therethrough and affording a valve seat on its under side for the air valve CZ. The operating connections c extend through the tubular housing b and comprise a rocker shaft provided with a rocker arm and a depending valve stem 7c upon which the air valve CZ is carried. This valve stem. j continues down and is provided with a shoulder g below the valve CZ and still farther down itv is threaded as at Zt to secure the adjusting nut t' and its companion ain-nut which regulate the position o't the spring abutment y' which holds one end of the spiral spring 7c that is coiled about thepvalve stem.

the tree Z is pivoted a rocking cross bar Q, one end of which is biturcated and straddles a pin on the sleeve 4. The opposite end is also biturcated and ordinarily engages under a ratchet tooth r ot the discharge valve stem. N ow, obviously when the rock shaft e is rocked by the turning of the crank t the air valve CZ is opened as shown in dotted lines at 5 and simultaneously the discharge valve n is raised. The air valve springs back to the position shown in the dotted lines at 6. The air pressure in the tank being relieved, the water readily flows in through the inflow pipe, which may be seated in the bottom of the tank as at fu. The discharge valve being open, the water now treelyiiows out until it allows the dropping of the tloat u which has fast to it an elbow fw pivoted at one end to the trunk of the tree and the elbow itself pivoting a free link which is guided in another branch y oi' the tree Z. Now, the end of this free link fr is ordinarily held under the ratchet tooth e of the discharge valve stem when this valve is raised by the full opening of the inlet valve, as indicated at 5, and when the float uis in the position of the full lines of the ifigure. This holds the discharge valve open. However, as soon as the water level drops the float u to the position shown in the dotted lines, this free link is drawn out from engagement with the ratchet tooth and allows the descent of the discharge valve n (for the valve stem in springing back to the position indicated at 6 has allowed the sleeve tand the cross bar to raise when the link as is dragged out of engagement with the tooth 2 by the descent of the float u). This closes ott the discharge of the tank. Consequently the tank immediately begins to lill. The water rises in the tank until it raises the upper float 1 which is suitably guided by a pair of guide pins in the arm 2 attached to theupright support which also serves as an overflow pipe. An upwardly extending pin guides the float in the bracket e. Now, this float l carries a weighted trip lever 7 adapted to engage the weighted trigger 7. It will' be readily understood that when the valve stem descends the T-head end of the trigger, byreason of the weighting at this trigger, swings above the shoulder g and thereby retains the valve stem f in its position indicated at 6 against the pressure of the spiral spring Za. Now again sov referring. to the rise of the water in the tank,

' it will be seen when this upper float lis keausedto rise, it carries the weighted trip lever 7 up with it, Yand this being'providedT with a hook on its end, grabs the end of the weighted trigger 7 and pulls theiTLheadl open when Athesame has been openeda discharge` valve, connections betweenthe air valvey andthe discharge valve so thatwhen fthe air.,\1al\'e 1s opened the discharge 'valve is opened, a trigger device orkeeping the*` discharge valve open, a Vioatwhieh when dropped pulls thetriggeroutiof engagement with the discharge valveand allows the descentoffthe same', and a secondffloat provided lwith a triplever which disengages the trigger from the air valve when the Water rises .'in. the tank.
